1. Failure reason

A) Whether the throttle valve is dirty;

B) Whether the throttle position sensor and its circuit have short circuit, open circuit or poor contact;

c)。 ECU failure.

2. Processing method

A) If the fault code appears, check whether the throttle valve is dirty; If there is dirt, please clean it up. If the fault is not solved or there are other faults, please find professional technicians.

B) Failure to clean the throttle for a long time will lead to an error in the throttle opening, and at the same time, air with impurities will enter the engine combustion chamber, resulting in abnormal engine operation. There is no strict limit on the frequency of cleaning the throttle, which has a lot to do with car habits and environment. Under normal circumstances, it is recommended to clean it once every 20,000 kilometers.
